[sdiy] PCB files

[ryan williams]

I would tell them to start over. place components in approximately the
order you would see them when reading the schematic and following the
signals. during my first layout, i got a little frustrated and just
placed about 15 resistors like that and finished with autoroute. That
is about the point I realized that pcb layout would take some practice
to get good at. It is common for me to place, route, then rip up
tracks and re-place and re-route some parts of the circuit. I did that
quite a bit with some of my first layouts. oh, and tell them not to
use the autorouter. I think its easier to get a good layout doing it
by hand anyway but it will take  a bit more work.

if i had shown something like this to my professors, i'm sure I'd get
yelled at in front of the class.
